/**
 * v1.4.15 phase-C5 — `/admin/backups` empty state.
 *
 * The previous build rendered a single-line `<p>No backups recorded
 * yet.</p>` inside the card. Brand-new admins didn't realise the "Run
 * backup now" CTA in the header was the way to create one, so the page
 * felt inert. The new EmptyState primitive duplicates the header CTA
 * inside the card so the action is right next to the explanation.
